I have been trying to understand how to solve the exercise. I took a look at the answer and apparently you are supposed to solve $y(t) = 0$.
I do not understand this at all, I tried watching some videos on parametric equations but it just doesn‘t seem to correlate.
I mean, yes in a normal function I would understand if we were to equal the function to zero and plug the resulting $x$ into the original equation to find the y-coordinates. But why would we only search for $y(t)=0$ here and not $x(t)=0$
I would appreciate some tips on how to solve these, thanks in advance!
